Abstract:
A process is provided for estimating a three-dimensional (3D) radiance field of a combustion process in an enclosure. An on-line intensity-temperature calibration is performed based on an association between an intensity of an image pixel and an actual temperature associated with a selected region in the enclosure. The intensity of the corresponding image is transformed to a radiance image based on settings of an image-capturing device and the on-line calibration. A registration and alignment estimation of the image is performed based on positional information of the enclosure. The radiance image is aligned based on the registration estimation. The 3D radiance field having voxels of the enclosure is estimated based on a two-dimensional to 3D transforming of the aligned radiance images.

Abstract:
Systems and methods of motion detection on encrypted or scrambled video data streams are provided. Some methods can include identifying macroblock size information for an encrypted/scrambled video data stream, and using the identified macroblock size information to determine a presence of motion in the encrypted/scrambled video data stream without decrypting and descrambling the encrypted/scrambled video data stream.
Abstract:
Methods, systems, and computer-readable and executable instructions are described herein. One method includes combining a plurality of images of a furnace into a composite image of the furnace, revising the composite image of the furnace to an intensity scaling, restoring a portion of the revised composite image of the furnace; and displaying a view of the restored revised composite image of the furnace to a user.
Abstract:
A method and apparatus wherein the method includes the steps of parsing a stream of compressed video, obtaining macroblock size information from the parsed stream, computing factors derived from the macroblock size, wherein the factors include a normalized bit size, a bit size ratio and a neighbor score, computing corresponding adaptive threshold values derived from the relative frame characteristics of the compressed video, comparing the factors derived from the macroblock size information with the corresponding adaptive threshold values and detecting motion based upon combinations of the comparisons when the factors exceed the threshold value.
Abstract:
Devices, methods, and systems for covert bar code pattern design and decoding are described herein. One covert bar code includes detector code and decoder code. The detector code includes a combination of responsive absorptive material and responsive reflective material, and the decoder code includes a combination of responsive absorptive material and responsive reflective material.
Abstract:
A system and method include receiving video images based on field of view of a wearer of a near to eye display system, analyzing the video images to identify an object in the wearer field of view, generating information as a function of the identified objects, and displaying the information on a display device of the near to eye display system proximate the identified object.
Abstract:
A visual system including a near-to-eye display supported by a frame adapted to be worn by a user such that each display is positioned proximate an eye of a wearer, a set of cameras supported by the frame, the cameras having different overlapping fields of view, and a processor coupled to receive images from the cameras and adapted to integrate and transform images from the set of cameras to provide a mosaic image for viewing on the display having a wider field of view than an individual camera provides.
